Title: Improvements in or relating to filter apparatus
IPC: B01D29/00
Filed: 1964-11-11
Abstract: 1,093,045. Travelling band filter. AJEM LABORATORIES Inc. Nov. 11, 1964 [Feb. 7, 1964], No. 33240/67. Divided out of 1,093,044. Heading B1D. In a travelling band filter in which the filter web (24) is entrained across a suction box 22 in a tank 20, a pump 134 draws filtrate from the box directly or from a filtrate reservoir 130 and delivers it to a user or to reservoir 130, depending on the setting of valves 135, 141. Tanks 130 and 20 have an overflow (142) which can transfer liquid either way depending on the levels. In Figs. 1, 2 the web (24) is disposable and wound from a supply roll 26 through tank 20, across a moving endless belt of parallel bars coacting with an upper opening in box 22, and to a discharge point. Movement is intermittent and manually controlled in response to falling pressure in box 22. A pipe 146 directs clean filtrate on to the underside of the web at the upper end of the box to ensure a good seal and to prevent air entering the box. In Figs. 3, 4 (not shown) the web (24a) is endless and entrained round the suction box which has two metal screens, above and below, by which filtrate enters the box through two sections of web. The box (22a) and the rollers supporting the web may be pivoted to lift them out of the liquid, about point (120), with the web drive motor acting as a counter-weight. The box has a flanged outlet co-operating, in the lowered position, with a similar flange (122) leading to the external pump (114), which is connected to reservoir (130a) as in Fig. 1. The web (24a) is cleaned by fixed jets (110, 112) directing water and air thereon. The outlet reservoir maintains filtrate flow during shutdown.

Title: Improvements in control of combustion furnaces
Inventor: BURCKHARDT CHRISTOF WALTER
Filed: 1956-10-31
Abstract: 814,485. Controlling burners. RHEOSTATIC CO. Ltd. Oct. 31, 1957 [Oct. 31, 1956], No. 33241/56. Class 75(1) The supply valve for an oil burner is controlled by a cold cathode electric discharge tube T the ignition electrode S of which is connected to a photo resistor PR fed from a derived voltage approximately 90 degrees out of phase with the anode voltage. An alternating current supply VI is connected to the anode circuit of the tube T which includes a relay R for control of the fuel. The supply voltage V1 also charges a circuit comprising a capacitor C1 and resistor R1 to give a voltage V2 across the resistor R1 and leading approximately by 90 degrees which is applied through a condenser C2 to the photo-resistor PR and a resistor R2 and so to the ignition electrode S of the discharge tube T. A diode D restores the initial condition to the ignition electrode on each negative half cycle of the voltage V2. After its peak the voltage on the ignition electrode falls away at a rate determined by resistance R3 and only if the photo-resistor PR has a correct intermediate value between a break and a short circuit with the ignition electrode voltage still have a voltage sufficiently high for ignition VS when the anode voltage has risen to the minimum anode voltage VA necessary for firing the tube in the main anode-cathode path.

Title: Improvements in time fuses for projectiles
IPC: F42C9/02
Filed: 1933-12-07
Abstract: 411,043. Projectile fuzes. SCHNEIDER ET CIE, 42, Rue d'Anjou, Paris. Dec. 7, 1933, No. 34477. Convention date, May 22. [Class 9 (i).] Relates to fuzes of the kind in which a percussion cap carrier is moved forwards towards a cocked firing pin by a spring at a rate controlled by a dashpot device until at the appointed time the firing pin is released and fires the percussion cap. According to the invention, the time is determined by an adjustment of the initial distance between the firing pin and the percussion cap, the rate of action of the dashpot having previously been set once for all. As shown, the percussion cap c is carried by a central tubular stem c<1> of a piston c<4> provided with a port c<5> adjusted once for all by a pin i, the adjustment depending on the thickness of a washer i<1>. The firing pin b is held cocked against a spring b<1> by a trigger d, d<1> and these parts are carried by a tube a<1> which can be screwed more or less into the body a of the fuze to adjust the initial distance between the percussion cap and the firing pin. When the projectile is discharged, a ring f sets back against a spring f<1> and is held back by a spring catch e<2>, after which centrifugal segments e<1> expand out of the way of a sleeve e. At the same time, a sleeve h in the tubular stem c<1> sets back against a spring g until a spring catch h<1> on the sleeve engages with a recess c<2> in the stem. During flight, after centrifugal force has moved a locking-bolt outwards, the piston c<4> is driven forwards by the spring g. At the beginning of this movement, a plug k, which normally obturates the flash passage and would vent off an accidental flash, is released by the tail end of the stem c<1> and is moved out by centrifugal force. At the appointed time, the stem c<1> reaches the sleeve e and moves it forward, thereby uncovering the trigger d, d<1>, which is moved out by centrifugal force and releases the firing pin b.

Abstract: 630,243. Gauging gear teeth. WIGAN, E. R. Dec. 29, 1947, No. 34551. [Class 106 (ii)] [Also in Group XX] A linkage for checking a curve approximating to an involute curve for a spur-gear tooth comprises an arm 4, Fig. 2, pivoted on a support 1 located over the centre of the involute base circle, a second arm 6 coupled to the arm 4 by a pivot 5 and carrying a tracing point 8, and a guide piece 7 pivoted in a bracket 18 and adapted to receive the second arm 6. The pivot 5 is adjusted relative to a scale on the arm 4 to lie at a distance approximately 0.8 times the radius of the base circle from its centre and on rotation of the arm 4 about the centre of the base circle with the centre of the guide-piece 7 over the origin T the point 8 traces a curve approximating to an involute. The end of the arm 4 may be integral with a plate 1 having cross wires 3 by means of which the pivot of the arm 4 may be accurately located over the centre of the base circle. In a modification, Figs. 3, the arm 6 is replaced by a triangular member P<SP>1</SP>, S<SP>1</SP>, T<SP>1</SP> having a rightangle at S<SP>1</SP>, the guide-piece 7 being located at S some 10 to 20 degrees away from the tooth origin T. The tracing point T<SP>1</SP> is thereby offset from the axis of the arm 6. In a further modification the guide-piece 7 instead of being located exactly above the tooth-origin T is mounted eccentrically in a frame which is free to pivot about another point slightly to the right of T. The approximation of the curve to an involute may be varied by the adjustment of the position of the pivot 5 along the arm 4.
